Varicam footage captured at 5.6Mb/s or 13.9Mb/s – RANDOMLY – by AJ1200 in FCP
I was not sure which forum would be the best for this post, but any insights will be appreciated. We have been capturing 24p footage from a varicam with a Aj1200 deck into our Fcp 5.0 system. However, in some cases the captured tape will show up as a red “unrendered” clip in our 24p (actually 23.98) sequence.
I had followed the advice of Kenstone who recommended to use the Easy Setup 720p24 option in FCP. Often, after I close the log and capture window, set the Easy Setup to 720p24 again, and re-open the log and capture and capture the clip, it would capture correctly (ie: not show up as red or “unrendered” in our sequence). However, after a few tapes that have been captured entirely the “wrong” way, I became convinced that it may a be a deck issue.
These settings are the same for all of our media: Frame Size = 960×720; Compressor = DVCPRO HD 720p60; Audio = 16-bit, 48k; Field Dominance = none; Pixel Aspet = HD (960×720).
The settings that vary are Video Rate and Data Rate. Half came into our system “correctly” at 23.98 (5.7 mb/sec) while the remaining footage is at 59.94 (13.9 mb/sec).
We will have to return the deck in 12 hours, and it appears that the more tapes we capture the more it seems we need to recapture (and pray it is doing it at 5.7Mb/s). So we are now frantic! Prompt reply will be greatly appreciated! Please help us — is this a deck setting issue?

This means that the DP shot half of the footage at 23.98 and the other half at 59.94. This frame rate is determined by settings on the camera, not FCP…the camera “flags” the footage as being a certain frame rate. If the camera flagged the footage at 59.94, and you have your easy setup set to 720p24, it will capture the footage at 59.94.
And if you drop 59l94 footage into a 23.98 timeline it will require rendering. But, after the render, it will be fine and match the rest of your footage. The pain is that you have to render at all.
Many DPs plan this, as they shoot 60p in preparation for SLOW MOTION.
